The Human Pollution Evaluation of Phosphorus in Surface Sediments of Nansihu Lake

Abstract

AbstractPhosphorus content and its species were studied for the surface of Nansihu Lake. The phosphorus contents in the surface sediment are 465.5-13068.3mg/kg, with the maximum value in Laoyun River, which was due to the waste water pollution from Jining City. The enrichment factors of organic phosphorus (OP) and NaOH-P are 6.5 and 9.0, respectively. The contents of phosphorus in other surface sediments are relatively lower. The enrichment factors of NaOH-P and OP are 1.0-3.7 and 1.3-6.0, indicating a minor human pollution
